Each Forest River RV is weighed at the manufacturing facility prior to shipping. A label identifying the unloaded vehicle weight of the actual unit and the cargo carrying capacity is applied to every Forest River RV prior to leaving our facilities.

The load capacity of your unit is designated by weight, not by volume, so you cannot necessarily use all available space when loading your unit.
